Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MAX501ACNG+ is determined by strict equivalence across the following critical parameters:

• Resolution: 12-bit conversion capability
• Channel Configuration: Single D/A converter
• Output Characteristics: Voltage output with buffering
• Interface Type: Parallel data interface
• Reference Configuration: External reference requirement
• Supply Voltage Range: ±11.4V ~ 15.75V analog supply compatibility
• Accuracy Specifications: INL/DNL performance of ±0.75 (Max) and ±1 (Max) LSB
• Settling Time: 5µs maximum settling time
• Package Compatibility: 24-DIP through-hole form factor
• Environmental Compliance: ROHS3 compliance and REACH unaffected status

The MAX502ACNG+ meets all these criteria and qualifies as a parametric equivalent substitute.
